Scientific tool/solver to solve “Single Variable Non-Linear Second Order Ordinary Differential Equations”. The app is very useful for engineers, scientists, economists to study the behaviour of a non-linear system encountered in practical problems. The app computes the value of Y and dY/dX at any given value of X (with given initial values of X, Y and dY/dX). The relationship between X-Y and X-dY/dX can be visualized using the “Plot Y” and “Plot yDot” functions respectively. The results along with the “Plot” can be sent to any e-mail id by using “Send e-mail” option. The app has a very rich and is very user-friendly UI (user interface). The results can be sent to any e-mail id by using “Send e-mail” option in main menu.

Please read the Equation format specified in help before attempting to solve complex non-linear equations.

★ Tips and Notes:•It is always recommended that the user’s uses as smaller difference in final and initial X as possible to get “Higher accuracy” and “Better Resolution in Plot”. This can be done using the step process as described below. •For example to find value of Y at 10 with initial value of X as 0, Y as 0 and yDot as 0 for d2Y/dX2 =Cos(X)*Sin(X). To get higher accurate results split the range of 10 into 2 “steps” (0 to 5 and 5 to 10). For first step, enter the equation and initial value of X as 0, Y as 0, yDot as 0 and final value of X as 5. Click “Calculate” to find value of Y and yDot at X=5 as “1.3180026397909919” and “0.45976788267781876” respectively. Now for second step, enter the equation and initial value of X as 5, initial value of Y as 1.3180026397909919, initial yDot as 0.45976788267781876 and final value of X as 10. Click “Calculate” to find value of Y and yDot at X=10 as “2.3858818461857414” and “0.1479794846781928”.•When the app returns a “NaN”, either the (i) Y and dY/dX value doesn’t exist at the final X or (ii) range is too large, try reducing the difference in initial and final X and use the step process described above (this is especially needed for functions with large curvature like tan and log).•Based on capability and limitations of Android system the maximum difference in initial and final X for “Calculate”, “Plot” and “Plot yDot” as fixed as “200”, “100” and “100” respectively. For Y and dY/dX at a range greater than 200, use the step process described above.
